Im currently converting some images to vector images They have asked can i provide them in a "layered structured illustrator file".
Im Relatively experienced with Illustrator and have never come across the term before im assuming they simply mean they want the ai. file with all the layers maintained?
Any help would be greatly appreciated.
Autotracing will create shapes that don't overlap. but this artwork could be created easily by drawing a grid and then adding the graphs to that. So that when deleting the graphs you won't get any gaps in the grid.
To have this structures sensibly you could put the grid and the text on one layer and the graphs on another one. You could fine tune this even further.
Maybe you just send the file to your client and ask them?
